Study on graft copolymerization of cassava starch with acryl amide by redox initiator

With cassava starch and acrylamide as raw materials,the cassava starch and acrylamide graft copolymerization were synthesized under the condition of redox initiation system.The paper studied the reaction temperature,concentration of initiator,and concentration of monomer,as well as the amount of reaction time of polymerization.The experiment results showed that:the copolymerization can be proceeded fastly in low temperature under the redox initiator system.At a temperature of 40 ℃,the amount of initiator for the 4 mmol/L,the amount of monomer for 85 mg/mL,and the reaction time is 3 h,the experiment can be one of the best conditions.
